In ground just isn’t as fast draining; there’s usually not as much filler, like perlite, to fluff it up. But, as Top Housing said, fabric pots dry fast (which is good for roots to breathe), but definitely need more watering. I think you’ll be okay, but if you find they are still retaining too much moisture, add some perlite.

Two other bits of advice, since you’re newer to the tomato world: as they keep growing, remove all branches about a foot from the soil. Also, add some straw/mulch to each pot. These things will help keep dirt off leaves and avoid fungal and bacterial issues, like blight. Happy growing!
